First Record of a Brachiopod (Brachiopoda: Terebrataliidae) in the Fouling of Hydrotechnical Installations in Peter the Great Bay, Sea of Japan

摘要

Large mature individuals of the brachiopod Coptothyris adamsi Davidson, 1871 were found in the fouling of a pier in Koz'mina Bight (Nakhodka Bay, Peter the Great Bay, Sea of Japan) in September 2006. The population density of the brachiopod in the fouling reached 100 specimens/m~2 and greatly exceeded the density of this species in benthic communities (4 specimens/m~2). This is the first record of a brachiopod on anthropogenic substrates in the Far-Eastern seas of Russia. It is of particular interest because (1) C. adamsi is listed in the Red Book of Russia and (2) construction of an international oil terminal is planned for Koz'mina Bight. The brachiopod population can be used to monitor environmental conditions during the construction and further functioning of the oil terminal in Koz'mina Bight.
